TIG Welding

TIG WELDING PROCESS (GTAW)

TIG AC, DC & AC/DC MMAW


Arc welding in inert gas with infusible tungsten electrodes (or simply TIG Tungsten Inert Gas welding) is a process in which heat is produced by an electric arc passing between a non-consumable electrode and the parts to be welded. The weld is achieved by fusing the edges of the parts to be welded, adding material if necessary in the from of rods. In MEMCO Welders the arc is triggered by a high voltage discharge to minimise electromagnetic interference. It ionizes the surrounding gas and allows current to pass. Alternatively, the arc can be triggered by touching the electrode and the part to be welded in a LIFT start process. During the electrode-work short-circuit phase, MEMCO welders reduce current to avoid damaging the electrode. 

Owing to the choice of DC (Direct Current) or AC (Alternating Current) power sources, TIG process can be employed for welding any material. DC is commonly used in TIG welding and is best for welding Ferrous material Nickel, Copper, Titanium and Magnesium Alloys. 

All power sources in the MEMCO range are capable of welding with square wave AC current for cleaner welds. MEMCO square wave limits heating of electrodes and torches to lower levels while contributing to higher welding speeds. MEMCO also optimises arc striking through its AC/DC generators once the electrode diameter is set.
